Title
(EN) LANDSLIDE PROTECTION BARRIER FOR SLOPING GROUND
(FR) BARRIÈRE DE PROTECTION CONTRE DES BLOCS DÉVALANT UN TERRAIN EN PENTE
Abstract
(EN)
The barrier (1) comprises supports each comprising: - an uphill post (7) having a base articulated to the ground (2) and a top connected to an uphill anchor point (9) by an upper uphill stay (18) and an uphill brake (10); - a downhill post (8) having a top articulated to and suspended from the top of the uphill post and a base connected to the uphill anchor point by a lower uphill stay (22). The endmost downhill posts are additionally connected to a lateral anchor point (11) by lower (24) and upper (23) lateral stays and a lateral brake (12). Nets (4) are slung between the downhill posts across the slope. The supports adjacent to the net loaded with landslide open up like a pair of compasses then pivot toward one another, the downhill posts remain parallel to one another.

La barrière (1) comprend des supports comportant chacun: -un poteau amont (7)ayant un pied articulé au terrain (2)et une tête reliée à un ancrage amont (9) par un hauban amont supérieur (18) et un frein amont(10); -un poteau aval (8) ayant une tête articulée et suspendue à la tête du poteau amont et un pied relié à l'ancrage amont par un hauban amont inférieur (22). Les poteaux aval extrêmes sont de plus reliés à un ancrage latéral (11) par des haubans latéraux inférieur (24) et supérieur (23) et un frein latéral (12). Des filets (4) sont fixés entre les poteaux aval transversalement à la pente. Les supports adjacents au filet sollicité par un bloc dévalant s'ouvrent en compas puis pivotent l'un vers l'autre, les poteaux aval restant parallèles entre eux.
